More specifically, as shown in the figure, the through hole 34 provided in the insertion hole 14 and the terminal portion 33 is made to correspond to the female screw hole 36 of the attached portion 35, and the bolt 31 is connected to the insertion hole 14 and the through hole. The screw 34 is screwed into the female screw hole 36 in a state of being inserted through. At this time, as shown in the figure, the curved portion 15 and the crimping portion 13 are directed to the insertion side of the bolt 31. As a result, the LA terminal 11 is connected to the terminal 33 of the vehicle electrical component 32 by the fastening force between the bolt 31 and the female screw hole 36.

When the screw 1 is completely screwed, as shown in FIG. 3B, the bent portion 15 is elastically deformed by the fastening force of the bolt 31, and the entire fastening portion 12 becomes flat. Here, as shown in FIG. 1, both ends 15 a of the curved portion 15 of the fastening portion 12
Both are open ends. For this reason, the fastening part 12
The fastening force of the bolt 31 ensures a flat shape. Therefore, as shown by the arrow in FIG.
Is applied to the bolt 31 to return to the original shape. Therefore, the contact surface pressure between the male screw portion of the bolt 31 and the inner wall surface of the female screw hole 36 increases, and the bolt 31 is less likely to be loosened.

(1) The fastening portion 12 is attached to the terminal portion 33 of the vehicle electrical component 32 in a state where the curved portion 15 is elastically deformed by the fastening force of the bolt 31. Therefore, in the fastened state, a force is applied to the bolt 31 so that the bent portion 15 returns to the original shape. Therefore, the contact surface pressure between the male screw portion of the bolt 31 and the inner wall surface of the female screw hole 36 of the mounted portion 35 increases, and the bolt 31 is less likely to be loosened. That is, the fastening portion 12 can have a function of preventing the bolt 31 from loosening. As a result, there is no need to use a spring washer when screwing the bolt 31 to the mounting portion 35, and the number of parts and the cost can be reduced.

Therefore, the curved portion 15 can be uniformly elastically deformed, and when the bolt 31 is completely screwed into the female screw hole 36, the fastening portion 12 can be reliably flattened. For this reason, the screwing failure of the bolt 31 can be prevented. Further, since a large contact area between the fastening portion 12 and the terminal portion 33 of the vehicle electrical component 32 can be ensured, the LA terminal 11 can be used even in a portion where a large current flows.

However, in this case, the curved portion 15
The one end 15a is an open end, but the other end 15a is not an open end and is continuous with the base 16 of the crimping portion 13. Therefore, the boundary between the curved portion 15 and the base 16 is unlikely to be elastically deformed, so that it is unlikely to be completely flat.
